amp blowing up


i turn off my preamp all the time before i turn off my amps and they never blow up. i have cj art mark 2 and wavac he833 single ended amps with trios never a problem i guess it does not matter how you turn things off any comments?

Biggest drawback of turning on/off in the "wrong" order is the pops one may hear in the speakers. I imagine this does cause damage, and over time will cause the speaker to die before its time. This scares me since I just sold my Monster 5000 which had proper power up/down sequence in favor of a CinePro PowerPro20 with no switched outlets. Guess I have to get off my lazy butt now:/ What I'll go thru for good sound.
My power conditioners turn the amps off first, and then all of the other components 20 or 30 seconds later. On start up, it's the other way around.
